Lead is dangerous to young children and adults and can lead to mental and physical problems throughout a persons life, Lead is most dangerous when it is in a dust form because it is easily inhaled into the lungs and because it is a dust it can remain on any flat surfaces undetected for a long period of time. My Concern I'm not sure whether my fathers house has lead coated paint on the windows or anywhere else within the house but nevertheless I'm not concerned. What I am concerned is that the wood that my father brings home to burn on the open fire may contain lead paint and as a result I have become very concerned, I clear out the ash from the bottom of the fire and em…

Here is an interesting theory. With the amount of chloride within the oceans, does anything think it could be possible for the early earth to make molecular oxygen via the reduction of chlorine into chloride?

Something that has always baffled me is, how could the earth form an iron core when there is so much oxygen present within the mantle and on surface of the earth? Wouldn't the formation of a metallic iron core have required a very substantal reduction potential? In other words, if one was to take all the average ingredients of the earth, and then heat and pressurize it, the iron would a very strong dominating reducing agent like hydrogen or carbon to be added to keep it from staying oxidized. With the core 1000 larger than the surface water, there should be a lot more hydrogen, carbon, etc., type compounds on/within the earth, maybe 1000-10000 times more. Venus can …

This is a neat, but expensive, little experiment used to make collodial gold which is a deep purple color and not the standard yellow color of gold. I do not have any pictures yet as I don't really have enough to get a good photograph of, but over time I will be trying to add more and more gold to this pile until I can get a nice photograph of it. Anyway, to start out you need a few ingredients: Gold metal (Any purity will do). Tin Metal (High purity is better). Nitric Acid (Concentrated). Hydrochloric Acid (Concentrated). Start out by making a small quantity of Aqua Regia with the HCl and HNO3. After the mixture has come together and cooled down, you add yo…

Is there any simple way to turn sulphurous acid into sulphuric acid? I mean the simple one, not so complicated that can be done at home...

In a chemical cell if we use copper as the anode and silver as the cathode and sulphuric acid as electrolyte. Then if any current occurs, the reaction will be: Cu + 2H+ -> Cu2+ + H2 but it doesn't seem logical, can Cu replace H+? Or if the set up as the above, any occur will occur and what's the reason?

I'm doing various experiments whit electrolysis, and as I don't have graphite electrodes, the metal in my electrodes goes into the reaction. At least that's what I think. I've tried Fe, Cu and Al electrodes. I started using NaCl dissolved in wather, and got that eerie Cl smell during the process. Then, I ran out of NaCl, and decided to try something else. I have a 25lbs bag of KNO3 sitting in the basement, and I went down there and grabbed a cup of the stuff, and dissolved it in hot wather. As you might know... When it was dissolved, the water wsn't very hot anymore... Anyhow... KNO3 seems to work about the same as NaCl, only it doesn't give of any Cl smell. …

I just made some beautiful white CuCl. It is currently under water and seems decently stable. However, the container I used to decant liquid got some CuCl on the edges and it has turned a light olive Green color. I have to assume that the rest will too when dry. What is the best way of keeping my CuCl white?

We know that Potassium is very reactive... so, is pure potasium bonded metalically? if so, then, how come it is very reactive? if not, what type of bonding?

I have heard of carbon-12 and carbon-14 but not carbon-13 Can you please help me.

Adding h2o2 to a solution of ammonium dichromate causes it to turn black- no ppt I dont think. Adding HCl causes it to turn brownish (originally orange). Whats happening??

What is the coordination number of copper in the oxalato copper (II)? I'm thinking 6 or 8 but can't quite be sure. Thanks for any help. Its made by mixing 90*c potassium oxalate monohydrate (K2C2O4.H2O) with 90*c copper (II) sulphate pentahydrate (CuSO4.5H2O) Cheers

What determines the strength of the metalic bond? As far as I know, the factors that affect the strength metalic bond includes 1. number of valence electron 2. size of the atom with these knowledge, i still don't understand why mercury is liquid at room temperature. Francium and caesium (cesium) are liquid. I think this is due to large atomic size and single valence electron. Bromine is liquid due to weak Van der waals forces. Galium is liquid at room temperature. What are the reasons? Any help?

Say, a battery using the electrolyte HCl, and eletrodes Mg, and Cu.. The Mg will decompose to Mg2+ and e-... the electrons bond with Hydrogen to form gas while Mg2+ bond with Cl- to become MgCl2... Ok, so how does that produce electricity? the electrons are used up to form various compounds... plz help

I think acids are ionically bonded..., but I have never seen solid acids... any help? thx

I've recently decided to take into consideration using a more durable water bottle made out of metal. Of course I'm too cheap to go out and buy a metal canteen I decided to use a bottle that was filled with Snapple Elements Energy drink, but now water. What I'm wondering is what type of metal this is made out of.. I don't really know what type of metal or anything. I don't even know how long until it rusts out. I do know however that sugars are acids and that acid eats away at metal and that it most likely has a higher pH level than water which is a neutral 7. So I'm guessing it will last longer with water than it would with sugar, but I'm concerened with the ope…

We know that carbon always exist in covalent bond with itself or other elements. But, how about Silicon? is silica a convalent or ionic compound?

Ar... A simple and silly question... I'd like to know whether sulphites is soluble in water...

Not sure if this is chem or physics but i came upon it in a chem book so here it is, Is electron capture and positron emission the same thing? like what are they and how do they differ? also what is a negatron? Cheers

I've got some hydrogen peroxide, I'm collected the O2 that came off. From this I think it is around 3-4% It only cost me £1 for 2li so Its ok ish.... Anyway, I remember bud (the avatar with the sanata hat on from NY I think) saying That to remove the water you just freeze it. Water FP: 0c H2O2 FP :-10c Well I tried this, as its such a low % it wasnt easy. I got a syringe filled it with peroxide and stuck it in the freezer. When it was hard it was like slush. Well I pressed the syringe to push the peroxide out of the ice. This worked in a way. I tested this on a silver plate and watched how fast the blubbles formed along side a drop straight from the b…

Would it be posible to create an energy source from thorium, using the properties of thermite (iron oxide and aluminum), only a transfer to thorium? I'm not going to test this, I was just peering at a table of elements. What would be the effects, except for the radiation emitted off of this?

does any one have a method of making HCL from NON-Indutrial products ? ? ?

Hello, This is a question about radioactivity. Basically, nuclei decay since they are unstable in order to achieve the proton to neutron ratio that stable nuclei have. I was just wondering why nuclei that lie above the band of stability ( neutron rich ) are unstable.... I know that the nuclei that lie under the band of stability ( proton rich) are unstable since the repulsion between the protons is greater than the strong force and therefore decay by ejecting protons, but in the case of the neutron rich nuclei what makes them unstable? cheers

I did an experiment in which I electroysed a plain table salt (NaCl) solution with different metal electrodes. Among the experiments there was an experiment with magnesium ribbon electrodes (both anode and cathode). When a sufficiently high voltage is applied, then a gas is evolved at the cathode (hydrogen gas) and the anode dissolves slowly and falls apart (formation of MgCl2). But, I also get a gas at the anode (approximately 1/3 of the amount at the cathode) and the really funny thing is, this gas is hydrogen! I collected gas from both electrodes and both can be confirmed to be hydrogen gas (they burn with kind of whoosh sound). The result of this experim…

Hi Does anyone have any resources on fuel cell technology? Can you trickle charge them? Size vs Output capacity? Thanks for your help, Rob
